New Trends in organ donation and Transplantation Juan Carlos Caicedo, MD FACS Director, Hispanic Transplant Program Adult transplant Surgeon (NMH) Pediatric Transplant Surgeon (LCH)
Overview • Introduction • Kidney ( Living / deceased/ combined stem cell) • Liver: whole, split, reduce size, living donor
Transplantation is offered to patients who: are in end-stage organ failure have no other surgical or medical option available to them have a limited life expectancy without a transplant have undergone a rigorous and thorough assessment process and meet all necessary criteria Who Needs a Transplant?
Type of donors Deceased (dead) donors -Brain dead donors: intact heartbeat & circulation, on ventilator • less than 3% of all deaths • -Donors after cardiac death: occurs in hopeless cases in the hospital where the decision to withdraw life-support is made (decision is independent of the decision to donate). Organ donation occurs immediately once the heart has stopped and the patient is declared dead Living donor -Patient chooses to donate one or part of an organ to someone on a transplant waiting list • can only occur with organs when removal will NOT cause grave harm to the donor-
United States Organ TransplantationOPTN & SRTR Annual Data Report, 2011
Patients on the waiting list on December 31 of the year (active listings only)
Transplants performed during the year (adult & pediatric combined)
End Stage Renal DiseaseDimension of the problem • >500.000 people in US • Options: Dialysis and kidney transplantation • US kidney waiting list: 105.124 people / 2013
Kidney Failure: Treatment • Kidney Transplantation “ Best option” • Replace all functions of the kidney • Increase survival and quality of life • Decrease complications • Cost effective
Incident ESRD Rate and Transplant Rate USRDS 2010 ADR
Whites :38% AA: 34% Hispanics: 19% Asian: 8% 2013: 105124 Waiting list 2012: 16485 Transplanted 758 ( 4.5%) Pediatric pts
Distribution of adult patients waiting for a kidney transplant
Organs recovered per donor (ORPD), by SCD, DCD, & ECD status
Delayed graft function among adult kidney transplant recipients
Living kidney donation • Laparoscopic vs Open - Safe - Less pain - Fast recovery - POD 1: Home - Smaller Incisions
Intended kidney transplant procedure type, & percent of intended laparoscopic procedures converted to open
Number of transplants from living donors, by donor relation All patients receiving a living donor kidney transplant. USRDS 2010 ADR
Sensitized Patients Very Highly Sensitized 36% Sensitized Total = 17,814 pts Sensitized 2010: 25%Sensitized
Options for Sensitized and ABO incompatible Patients • Wait and hope • Desensitization • Live Donor • Deceased Donor • Live Donor Paired Exchange • List Exchange • Wait and hope • Desensitization • Live Donor • Deceased Donor • Live Donor Paired Exchange • List Exchange

Sequential kidney/HSC in HLA matched related • Simultaneous kidney/HSC in HLA mismatched Northwestern Clinical Tolerance Protocols
Current Enrollment – 20/20 • First patient enrolled January 2008 • HLA identical siblings • Excluded if high risk of recurrent disease in the allograft (role of immunosuppression in preventing disease recurrence) HLA-Matched Protocol PI: Joshua Miller
Simultaneous FCRx +Kidney Transplant Processed donor leukopheresis product/marrow enriched for HSC, FC and progenitors (FCRx) HSCT mobilized, collected, processed, & cryopreserved (> 2 wks before Tx) Conditioning Fludarabine, cytoxan, 200 cGy TBI d0 d +1 Perform Transplant
Outcomes among adult kidney transplant recipients: deceased donor
Outcomes among adult kidney transplant recipients: living donor
Liver Transplantation • Type of donor: Living vs deceased donor • Type of graft: Partial vs whole organ

Partial Grafts / Liver transplantation (LTX) • -Reduce Size Ltx • -Split LTx • -Living Donor Ltx
